Nant-y-Moch (in English = "the pig stream,") is the name of a small river in north Ceredigion which has given its name to a 66.8 square kilometre reservoir in the Cambrian Mountains, Wales which flooded the valley of the eponymous stream. The dam is about three miles north of the village of Ponterwyd. The reservoir forms part of the Cwm Rheidol hydroelectric power scheme and the headwaters of the reservoir includes the source of the River Rheidol.

History

Nant-y-Moch was created in 1964. The construction of the dam flooded the valley south of it, which included the small village of Nant-y-Moch. The contents of the graveyard which was to be submerged were relocated to the chapel at Ponterwyd, and a number of Cairn were painstakingly moved, some of which dated back as far as the Iron Age.
